&lt;!-- THREE STEPS TO INSTALL IMAGE CYCLER:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the onLoad event handler into the BODY tag
  3.  Put the last coding into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;
